摘要

The microhardness on the (010) and (001) planes in K2Co(SO4)(2) center dot 6H(2)O crystal has been measured by the Vickers indentation method. Its values are, respectively, 11500 and 1300 MPa. No microhardness anisotropy of the first kind is revealed on either plane. The fracture geometry under indentation by a spherical indenter and Vickers and Knoop indenters is studied. The crystal has lower brittleness than the isomorphic Cs2Ni(SO4)(2) center dot 6H(2)O crystal.
